1. After the engine is turned off, the key cannot be pulled out. This phenomenon often occurs in cars with automatic transmission. The reason is that the automatic gear does not really return to its position in P gear. Sometimes it looks as if it has returned to its position, but it does not touch the electronic sensor, or there are coins and other things in the gear slot to hinder its return. There are things in the car that should be cleaned and checked if they are dirty; Run the car, shift the gear again, make sure it returns completely, and then pull out the car key buckle.

When parking, the angle of view of the car will not be adjusted, which makes the steering wheel not in the right garage when parking, resulting in the steering wheel locking and the difficulty of rotating the key.

2. The key cannot be turned. When the key is inserted into the key hole and ready for operation in advance, it is found that the key cannot rotate. In fact, the steering wheel is fully automatically locked. Basically, most cars have this function, mainly to guard against theft. When the car stops and the steering wheel turns to a certain angle of view, the full-automatic locking will be turned on.

If the key is pressed, the starting motor cannot rotate. The solution of fully automatic locking of the steering wheel is not very difficult. First insert the key into the key hole, rotate the steering wheel up and down, and twist the key with your right hand until the key can be rotated and the steering wheel is opened. If you find that the key can't be rotated, you don't have to rotate the key astringently. This can easily cause the key to bend or even break.

3. The steering wheel locks automatically because the key of the automatic transmission cannot be opened. Most cars have this function, and the key goal is anti-theft. The solution is to insert the key into the key hole, rotate the steering wheel up and down, twist the key with your right hand until the key can rotate, and the steering wheel will open.

The basic concept of the key is: a small radio wave is sent from the buyer's side, the car antenna receives the radio wave signal, and the electric actuator of the system performs the opening and locking posture after the identification signal code of the electronic device control board ECU.
